The doors usually have a frame made of wood moldings that attach to door frames and walls. The framing of a door used to hold the jamb in place and provide a decorative stamp. The door frame is nailed with finishing nails 1 and 2 inches. It must be difficult to not to crack the molding, nailing nails and install the farthest edges of the moldings.
Moldings that form the frame are cut with a miter box and a hand saw or a miter saw, and installed with a hammer or a pneumatic nail gun. The pneumatic drill can help you avoid having to use an awl or nail to bring the nail head and thus the cover with wood pulp.
Cutting the corners of the door frame is made to a 45 degree angle when it is attached together, or at right angles if you install a rosette at the corners of the frame to give a more rustic character. The framing is nailed to the jambs with 1 / 8 inch from the inner edge of it. You start with one of the uprights, then the head, and finally another jamb, allowing you to adjust the seal cut at 45 degrees to make it as tight and thus less visible.
Some use white glue on the joints cutting the door frames so that they can not move with the left. The nails are 1 inch to secure the jamb and framing nails from 2 inch to attach the wood to the wall framing that is usually covered with gypsum. If the surface of the wall is thicker, use nails longer.
Once the door frame very solid, you just have to use a plow your nails and hammer to drive a finishing just below the surface of the wood molding to put a pulp and hide their heads and bright nail. Then you can stain, varnish or paint the door frame.
